To all z'uhom it may concern.-

Be it known that I, GARDNER'AJ GIBBS, a citizen of the United States,and a resident of Livonia, in the county of Livingston and State of NewYork, have invented certain new and useful Improvements in Separators,of which the following if a specification.

My invention relates to that class of machines used for sorting beans,peas, and various grains and separating fromihe'm foreign substances,and has for its object to provide means for quickly andaccuratelyaccomplishing this separation.

In the accompanying drawings, Figure 1 is a side elevation of themachine; Fig. 2, a top view; Fig. 3, a section on'the line 3 3 of Fig.2; Fig. 4, a section on the line 4 4 of Fig. 2, and Figs. 5 and 6 partshereinafter to be described.-

In the drawings is shown a machine illustrating my invention, in which Arepresents the main stationary frame of the machine, on which aresupported the various parts. Within this main frame and pivoted to itsend bars A A by bolts 1) b, so as to be capable of transverse tilting,is a second frame composed of end pieces B B and side pieces B B A blockb is shown (see Fig. 1) between the end piece B of said tilting frameand the cross-piece A through which also the bolt 1) passes. .Thebolt 1) lies within a slot 19 in the" cross-piece A of the stationaryframe, (see Fig. 4,) so that this end of the tilting frame may be raisedor lowered through the length of this slot. The frame may be secured atthe height desired by the nut 6 which is shown with a handle attached toit, by which it is operated. A handle-bar b is attached to the other endof the tilting frame and the bolt 19 passed through it and thecross-piece b Said handle-bar projects outward beyond the stationaryframe in the manner shown in Fig. 1, affording means for tilting theframe. It may be secured in place by a nut b upon the bolt 6 whichlatter lies in a slot in the post A, which permits the adjustment. Theslot is not shown in the drawings.

It is desirable that the frame B should be capable of both longitudinaland transverse tilting in order that it may be adapted to the separationand grading of different objects,

some of which roll much more readily than others.

Secured uponshafts c c, which are transversely journaled in the sidepieces 18 B of the tilting frame near its ends, respectively, arerollers C 0; Attached to the end of the shaft 0 and extended beyond thestationary frame a crank c is shown, with handle 0 by means of which theroller 0 may be revolved. The device can of course as well be driven byany other power, and suitable attachments therefor can be readily madefor it. Between the rollers C O and supported by the side piece B of thetilting frame is a table D (see Figs. 3 and 4) for the support of theendless belt E, which is passed around the said rollers and over saidtable. The upper surface of this endless belt constitutes a movablecarrier on which the objects are separated in the manner hereinafter tobe described and from whose surface they are conducted when separationhas taken place into distinct masses. Between the edge of this table andthe side piece 13 of the tilting frame a space 19* is left, as shown inFig. 4.

Chutes E E are attached to the tilting frame in the position shown inFigs. 1 and 4. The upper edges of the inner faces of the said chutes areplaced somewhat below the upper side of the belt, (seeFig. 4,) and theirouter surfaces are carried up above the lower edge of the side piece Bof the tilting frame, as is shown in Figs. 1 and 4. Extending along thebottom of the table D and resting on the top of the inner surfaces ofthe chutes E E is the inclined surface or platform F. (See Figs. 3 and4.) A partition G (see Figs. 2 and 3) is placed across said platform. Fat a point between the chutes E E. Attached to the end of the tiltingframe beneath the roller 0 is a third chute H, and above the belt andsupported on the main frame A is a hopper K, provided with a gate orslide it, as indicated in Fig. 1, wherebybeans are dropped in regulatedquantity upon the belt.

The functions of the several parts will be clearly shown in thedescription of the operation of the machine found hereinbelow. v

In my machine the separation is accomplished by spreading out ordispersing the beans upon the belt during their passage on IOO it, thuspermitting the round most perfect beans to separate themselves from themass and to roll off from the belt into receptacles placed to receivethem, while the imperfect beans and refuse matter remain upon the beltand are carried to another chute through which they are discharged. Bythe device I employ the beans are repeatedly thus spread out anddispersed while on the belt, and the separation is thereby rendered verycomplete and thorough. To accomplish this, I place back and forth acrossthe-belt in Zigzag order, alternately, beginning on the left beneath thehopper K, guides L and M. (See Figs. 5 and 6.) One end of each guide Mlies within grooves in the side piece B, and the other end is set inaslotted block m, whereby the guides are retained in position. One endof the guides M also fits within notches Z in the guides L, and theguides L in turn are slipped within one of the notches m shown in theguides M. In this way the guides are fixed in place, the several notchesshown in the guide M for the reception of the end of the guide L makingit possible to change the angle of the guide L with reference to theline of movement of the belt. The lower ends of both guides are setclose to the belt E; but the manner in which they are cut away (shown inFigs. 5 and 6) leaves passages through them near the upper and loweredges of the belt alternately, as shown by the arrows in Fig. 2.

The operation of this machine is as follows: When the tilting frame hasbeen set at the proper inclination and its lower end adjusted to theheight desired, the belt is put in motion and the beans are allowed tofall from the hopper K upon the belt. They are carried on it along thefirst guide M until they reach the passage shown by the arrows in Fig.1, through which they pass. As they come out from the passage into thespace N, between said guide M and the next guide L, they are dispersedacross the belt. The round most perfect beans will then roll down theinclined surface of the belt and falling upon the guide-surface Fbeneath will be directed into the chute E The remaining beans and theforeign substances mixed in with them will be carried forward by thebelt and collected against the guide L, along which they will move tothe next passageindicated by the arrow. The beans will be carried alongsaid guide L in a thin line from which the round ones will soon easilyseparate themselves to roll down the belt. Entering the space N theyarecarried up along the guide M to the top of the belt again, to be oncemore scattered across the belt, so that the round beans may roll offinto the chute E. The beans are thus carried successively to the spacesN, N N ,N*, N N, and N. In the spaces N, N N and N they are spreadacross the belt, so that the round ones may roll down the inclinedsurface of .which remain upon the belt.

the belt, while on each of the spaces N, N N and N they are carried backto the top of the belt, and the separation is facilitated during theirpassage along each of the succeeding guides L L and L. The arrows inthese spaces indicate the course of the beans. That of the round beansis indicated by the lower arrow in the spaces where two arrows areshown, while the upper one indicates the passage of the beans andforeign substances It will be noticed that each successive guide of thepattern L, beginning on the left with the guide L is set at an anglewith the next forward adjacent guide of the pattern M which is moreacute than was the last. This adjust.- ment is accomplished by placingeach successive guide L L &c., in a lower notch m in the adjacent guideof the pattern M than was the last. In this way the path of the beansacross the spaces N N N N is turned more directly across the belt ineach successive space as the beans progress, thus increasing thetendency to roll them from it. The partition G, hereinbefore described,divides that port-ion of the inclined surface from which the beans arecarried to the chute E from that portion from which they are carried tothe chute E. Inasmuch as the most perfect beans will be the first toroll from the belt they will be carried to the chute E, while aninferior grade, which will not roll from the belt until they encounterthose guides which are set at great er inclination,are turned into thechute E. Thus the beans are sorted into two grades, and refuse matterand those beans (split and rough) which are below grade are carried offon the belt to the chute H, through which they are discharged. Thehopper E and the portion of the inclined surface F which feeds it arelonger in the drawings than the hopper E and that portion of theinclined surface over it. This proportion of these parts is recommendedfor the reason that all the beans of the first quality are not as likelyto be drawn off from the mass of beans when first spread apart in thespaces N, as is the case in the succeeding spaces, when the number ofthe beans upon the belt has been reduced, thus permitting their freermovement.

This device is well adapted for separating any objects which are capableof rolling easily when perfect-such as pills, marbles, and shot.
